Exemplary embodiments of the present application will be described below with reference to the accompanying drawings. It should be understood, however, that the present application may be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein. It is also to be understood that the embodiments disclosed herein can be combined in various ways to provide further additional embodiments. Throughout the drawings, like reference numbers indicate identical or functionally identical elements.

The suspension mechanism with spin function shown in fig. 1 to 5 mainly includes: the upper movable beam 10, the lower movable beam 20 and the independent beam 40.
